Application inea Apri; 29,

My invention relates to b edsteads and more particularly to a bedrail lock whereby the bed rails may be detachabl'ysecured to the bed posts ofthe bedstead. -f Y 5 lOne of the objects of the present invention is to provide a simple and efficient construction of a bed rail lock for securely fastening the bed rails to theposts of the bedstead.

Another object 'of the invention is'to proerably made ofa single piece of sheet metal and adapted to be secured tothe bed post of the bedstead in combination with a novel forni of' a bed rail locking member whereby the locking member engages Vthe bracket to v form a' rigid connection between the bed rail l'and bed post.

' A further object of the inventionis to provide an improved form of Aa bed rail lock in which the bed rail may bei reversed or changed, end -for end, so that'the horizontal ange of the bed. rail `may be`positioned onl the top or on the bottom when attached to the respective ends of the bedstead when such a change is required." y

` A further object of the invention is to yprovide la novel form of Asupporting"bracket in kwhich means are provided for detachably connecting a transverse brace rail which extends across the posts atjthe headfand the l'foot of the bedstead vso that this cross rail may be dispensed with or attached according to the requirements. Y

. In illustrating one embodiment of my invention, 'I have shown the same in connection with a bedstead or bedsteadpost which is yin the form of metal square tubing, but it will, of course, be understoodthat the invention is'applicable to metal round tubing as well as wooden bed posts. In carrying out mylinvention,` I have shownY my improved formof supportingbracketlO secured to the metal tubing orbed post 11. This bracket 10, I prefer to make of a single piece of sheet metal in the interest of economy inmanufac-l ture, but thesame may bev readily made in kthe form ofa metal casting.

In the preferred form, this 'bracket is provided with a vertically extending lock engaging Wall 12 which jin turni is provided with a vertically extending .slot 13.. One edge of lthe slot'as shown atlil extends in a vertical plane, while the other edgeas shown at 15 extends at a slight angle with respect to the ver-l tical, so "as Ytoi'form a bearing yor camming surface for; the locking 4member .hereinafterV described. The outer edge ofthe vertical wall 12 of the supporting bracket 10 extends in a vertical'plane for the purposeof engag- Ing the locking member 1n a manner herelnafter described. It will be noted thatverti- K,

cally extending edge 16togetherwith the in` lclined edge 15 forms a substantially verti- 'at 17 .bent at right angles with respect to the lockengagingwall 12. This portion 17 sustains the vmajor part ofthe vvertical strain 'on the bracket l0. Formed integrallywith Y Y l the lock engaging wall 12 and bent atright Fig 3-is 'ai-top plan view of the construcangles with respect thereto `and also at right -/angles to the port-ion l17 of the bracket is a rhorizontal portieriv 18... Formed integrallyl iwith the portion 18 of the bracketl() and atl right angles with respect thereto is a lateral vby means of bolts 20 which extend through Cie ysuitable apertures in the post and engage threaded apertures in the metal strip 21 within the post.

It is quite obvious that means other than those shown in the drawing may be employed for securing the bracket to the post,

My .improved locking member. which cooperates with theabove describedbracket for securely and detachably locking the side rail to the bracket comprises a locking member l which is provided on one end-with a-lateral projecting tongue 23 which is arranged at right angles with respect to the main body'v portion of the locking member. Forinedon the upper and lower ends ofthe'locking member l,22.-adjacent' the tongue 23v are `two shoulders 24. The locking member 22 is secured to thebed-side rail 25 by havingthe `'tongue 23- eXtend through a vertically eX- tending rectangular slot 26 formedin the bed rail. The locking'ineinber22 is heldin `spaced'.relation withrespect to the side Vof Vthebed railbyhaving the shoulder l245 of the V,lockinggmember engage the-side of the bed rail,asclearlyqshownin Fig. 3. The other.

q end of the locking member 22isheld in spaced relation with respect to the side `of thev bed rail 25 by an offset portion 27-which is pref- .erably pressed out laterally. from the material a rivet 28. i This depressed or odset portion ofwhichfthe vlocking,member 22 jis made.

This locking ineniberfis securedfinposition:

against .displacement from the side rail 25 by g 27. is provided with taperedfor ycammingl sur- Afaces 29 andBO respectively. These cam- Lming or bearingisurfaces .29 Aand 30 diverge with respect to each other so that the bracket is made reversible or more strictly speaking Y sonthat'when itbecomesnecessary to change the side bed rail, endforend, so that the horizontal flange of the bed rail may be changed .f

from the top to the bottom thereof or vice versa,lthese-camming surfaces will engage.

-the inclined surface 15V of the bracket `and inipinge or clampthe tongue 22 between .i ytheright angularly bentportion 30 of the locking member 22 and the camming surface-A Y 29 asclearly shown in Fig. 1.

'1 VFrom the above description, it will be seen 1 that when the locking member 22 is attachedV or secured to the side rail 25 so that the hori-` Y zontal flange 25is on the top side thereof Las shownin Fig. ,1 and the offset portion with :its camming surface 29 positioned toregister.. with the.y slot 113 of the ybracket 10, 4the verti- 'ca1lyeXtending tongue 22A of'the bracket ,f 10 will/.register with .the slot 2 formed be-v tween the member 22 and the vside rail 25, and

. when the side rail is pressed into engagementy with :the bracket, the camming surface 29 engages the inclined surface 15 of the tongue 22' and, impinges or locks'the side rail 25 to the bracket in such a manner toform substantially a rigid connectionbetweenvthe post-andV Athe side rail, Lthereby eliminating all possibility of vibration between these parts. lt will also be noted that by reason of the relatively long camming or bearing surface 29 being in engagement with a corresponding length of surface 15, the possibility of wear on these'surfaces is reduced to aniinimum.

ln Figs. 1, 2. and 3, I have shown a transverse brace 31 which extends between the posts and is in the forni of an angle having onelegithereof secured-by means of a rivet 33 to the horizontal portion 18 of the bracket 10. 4*The other leg 0f the angle as shown at Seis secured by the bolt 20 and contacts with Vthe ear portion 19 of the bracket. The translverse brace is .preferablybowed .as shown at A34: so asto accommodate thebed spreadso thatI the same may hangdownwardlyat both ends of the bed andcover the. bedding.

t In the modified form shown in' Figs. 5 and 6, the horizontal portion 18 of. thesupporting bracket 10 is provided with a key hole slot 35 so .as to, permit the transverse. bracel to be detachablyV secured-t0 the bracketvbecause in vsoine bedstead,-constructionsythis transverse brace is dispensed-- with and by .having ythis transverse brace, i detachable, `it may -be ..readily taken olf or if the construction ofthe bedsteadgrequires it, itl` maybe easily positioned andsecured to the supporting bracket. l 95 The vtransverse Abrace 31 is` provided-with a pin 36 having a head thereon which is of relatively smaller diameter; than the vlarger ciry, cular opening in the ,key hole slot sothat Athe .head .thereof-may beffreadily slipped =into- Ethekey 'hole slotand the lower, leg 37 of. the

transverse braceymember 31 secured to the ybed post yr11-,by means-)of thelbolt-20.

Theoperationgof-,my Limproved-bed rail lock will be apparent from theabove descriptiony and the .advantages arising from having a locking member with a relativelylong bearing or zarnining surface rcontacting'with a cooperaitinginclined surface of the tongue formed on ,the supportingbracket insures afirin lock-v 1 i-ng-.fi-zonnectionll between .these l `detachable parts.

While in the abovespeciiication, Lhave described one embodiment; whichV my, inven- `tionvinay` assume injpr-actice, itwilhof course,- v be understood that .thefsame is cap able ',ofmodification anduthat modication'gmayfbe.made :without departingfrom the spiritand scope of my invention as expressedin the following bent portion engageable with one edgeof said tongue and an offset cammingportionengageable with .the.= -1nclined-e,dge ,off` said gularly bent portion enga eable with one edge of said tongue and an o set portion engageable With the other edge of said tongue, said rail being provided with a slot, a tongue on said bent portion lying inthe plane thereof and forming a Continuation thereof secured in said slot, and means extending through said offset portion for further securing said plate to the rail. e f l In witness of the foregoing I aiix my slgnature. f
